PNEUMATlC MILKER.

SPECIFICATION forming part of Letters Patent No. 439,552, dated October28, 1890.

Application filed January 22, 1890. Serial No- 387,727. No model-I T0all whom it may emwern:

Be it known that I, JULIUS 'l. POMEROY, of Edger-ton, in the county ofRock and State of Wisconsin, have invented a new and Improved PneumaticMilker, of which the followingis a full, clear, and exact description. yinvention relates to improvements in milking-machines; andtheobjechofmyiuvention is to provide a simple and efficient device that may beeasily connected with the teats and udder of a cow, that will quicklytransfer the milk from the udder of the cow to the pail of the machine,and that will prevent the milk from being contaminated by foreign andoffensive matter.

The invention will be hereinafter fully described, and specificallypointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, iii-which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a vertical section of the machine; Fig. 2, a detail view ofthe end of one of the milking-tubes that is inserted in a teat; Fig. 3,a plan view of the machine with the pumptube in section on the line.131: of Fig. 1, and Fig. l a detail view showing the manner ofattaching the top cover to the pail.

The pail A is provided with a suitable handle B, by which it maybecarried about, with a spout C, through which the milk is poured, andwith a removable cover 1), to which is attaehedthe air-pump tube E. Thepail A also provided with a shoulder it around the opening in the topupon which the cover I) rests and with two upwardly and forwardlyextending lugs I, which are attached to the top of the pail uponopposite sides of the opening in the top, and which extend above thecover I). The lugs b are each provided with a thumb-screw (I, whichextends downwardiythrough the lugs and engages the laterally-extendingears 6 of the cover D and holds the cover tightly upon the pail. Thecover I) is provided upon opposite sides with an ear :3, which may beturned beneath the thumb-screws (I of the lugs h when the cover is to befastened in place, and with an annular shoulder f, which extends aroundits lower edge and tits closely upon the shoulder a of the pail. \Vhenthe cover is to be fastened to the pail, a packing-washer g, of rubberor other suitable material, is placed upon the shoulder a of the pail,and the cover D placed upon the pail so that the shoulderf will restupon the packing-washer. The cover is then turned till the ears 6 arebeneath the thumbscrews 1?, when the thumb-screws are turned down, and,impinging upon the cars, they will fasten the cover securely upon thepail, and the packingwasher g will insure an air-tight joint.

The tube E opens through the cover D into the pail A, at which point itis provided with an ordinary check-valve 72, which opens from the pailinto the tube. Above the valve 71 and movable vertically in the tube E,is a piston F, which is provided with an ordinary suction-valve '1', andwhich is pivoted by the cross-barj to the piston-rod II, which ext-endsupwardly through the removable cap E at the top of the tube, and isprovir. .d with a suitable handle J, by means of which it is operated.This makes a very simple airpump, and by grasping thehandle J and movingthe piston up and down in the tube E the air may be pumped from thepail. I do not confine myself to the use of this pump, however, as anysuitable pump may be employed. 5 -,Opening from the upper part of thepail and upon one side thereof are four proj ecting metal tubes is, uponwhich are fitted four rubber tubes is, whichare to connect the pailAwith the udder of acow. of a convenient length, are provided at thefree ends with a metal. nipple l, and are also provided with a sectionof glass tube on near the pail, which enables the operator to see if themilk is flowing properly through the tubes. The nipple is provided witha spreader l', which extends outwardly from the end thereof, and whichconsists of two fine wires having their ends attached to the tube, andhaving their outer extremities bent to form a dull point. The wirescomposing the spreader l are placed at right angles to each other andare so bent that the formed spreader will have an oblong shape, and willterminate in a dull point.

The machine is operated as follows: The pail A is placed upon the flooror ground at The rubber tubes 7.; are

2 eeeese one side of the cow and the nipples Z and spreaders l insertedin the cowsteat. The nipples will fit closely in the vent of the teatand the spreader will extend upwardly into the milk-receptacles and holdthe tissues apart so that the milk will flow through the nipples andtube to the pail. When the tubes are connected with the cowsteats theair-pump is worked, thus creating avacuum in thepeil, and the suctionfrom the pail, combined with the action of the spreeders, Will cause themilk to how quickly and freely to the pail till the cow is milked dry.It will thus be seen that the cow will be quickly and easily milked, andas the pail is .tightly covered the milk will be entirely I free fromcontamination. Vhen the pail is to be emptied, the thumbscrews d areloosened and thecover D re moved.

Having thus described my invention, What I claim as new, and desire tosecure by Letters Patent-,is- 1 V 1. In a miike'r, a. tube Z, providedwith aspreader Z, consisting of two wires looped and crossed at theirouter ends and secured at their inner or free ends to the tube, thewires being disconnected attheirtpoint of crossing,

substentiallyas set forth.

2. The combination, with a milk-receptacle provided with anstir-exhausting mechanism, of tubes leading from the vessel and providedattheirouter ends with spreedeisconsistiug of looped and crossed wiresdisconnected at their points of crossing and connected at their innerends with the said tubes, substantially 5 as set forth.
